How does the full-color LED display display graphics and text?
The led display has been developing rapidly in China for 6-8 years. It is a must-have product in many industries, especially hotels, stations, airports, real estate, government units, etc. It is even more necessary. A led display After the screen is installed, it not only brings more convenience, but also instantly upgrades the grade, if not, it really won't work! However, the LED display is still a high-tech product. Most people outside the industry still don’t know how to display the LED display. It can not only display text, but also display pictures, videos, and even directly broadcast events, etc. , It can be said that almost any file can be played. Let’s explain how the led display screen displays, so that everyone can understand the principle!
The above picture is a single label light tube of LED display screen, which contains a secondary light-emitting tube, which is packaged by gold wire and bracket. This is a full-color light tube, including three kinds of RGB light-emitting tubes. If you have a little knowledge of the three primary colors, you should know that RGB is a primary color, which can form 16.77 million colors. All colors that we can distinguish can be displayed
This one is a box made up of several LED modules, and a special power supply and control card are installed on the back of the box. The quantity of control card and power supply is different for each model. There will be some differences in price and performance. Therefore, some customers may encounter manufacturers who cut corners. Therefore, it is not necessarily a good thing to blindly ask for the bottom price It may be the customer who suffers the loss!
When the LED display screen body is partially assembled, it is like the above, then here, the display screen is very easy, of course, you don’t need to dig into it so thoroughly, just understand it! The following is the specific operation steps of the display screen and video
The preliminary preparation and installation and debugging of the LED display to display pictures, videos, etc. are all done by the engineer, so there is no need for users to worry, we only need to open the corresponding led display control software on the PC, of course the engineer has installed it Well, the PC computer receiving the card is not suitable for any computer. It is best to have a more powerful computer configuration, which will be more smooth and easy to operate;
The user edits pictures, texts, videos and other content through the led display control software on the computer and sends them to the receiving card of the led display. As mentioned earlier, there is a driver IC on the module. After the control card receives these playback content, it drives the ic It will be controlled and scanned, and then the content will be presented on the front of the led module, which is displayed by emitting different colors of light. The TV station we usually watch receives signals also through different scanning methods to scan out the broadcast information and then present it on the TV On the screen, the display principle is the same!
The led display control software is something that the customer’s operator needs to be familiar with. The manufacturer will also give away operation manuals, conduct operation training and provide long-term training and maintenance services. How to display pictures and videos on the led display is actually a very simple matter. We do very little, and most of the technology has been done by engineers. Many customers are just confused when they first come into contact with it. Decisions are more difficult. After a period of operation, it feels very simple, almost no difficulty! Hold on for a while, everyone is a teacher after getting familiar
